In the character generation process for the Inquisitor class, I was faced with a question, the answer to which I'm not entirely sure.
I used Conversion Inquisition, which grants me:
Charm of Wisdom (Ex): You use your Wisdom modifier instead of your Charisma modifier when making Bluff, Diplomacy, and Intimidate checks.
After that, I added the archetype Heretic for the Inquisitor, which grants me:
Lore of Escape (Ex): At 1st level, the heretic uses every trick she knows to escape those now pursuing her. She adds her Wisdom modifier on Bluff and Stealth skill checks in addition to the normal ability score modifiers.
For Bluff checks, this would mean adding a Wisdom modifier twice. Is that allowed by the rules?
